several possiblities, avi class information is stored at the end of the file,
after all the image data, if the file was truncated during download then the
information is not present, if you tried to play the partial file during
download then your media player has appended classinformation at the point
where the file was then, so it does not match.,,
However most likely is you do not have the codec installed on your system that
the clip was coded in so your media players cant decode the file, you can
download a free utility called 'gspot codec appliance' that will tell you what
codec the file was coded in, and then install that codec, dont bother
searching Microsoft they do not support any of the new defacto standard codecs
on their site
